How to Display Disk Slice Information

Become superuser.

Enter the format utility.

Identify the disk for which you want to display slice information by selecting a disk listed under AVAILABLE DISK SELECTIONS.
Specify disk (enter its number):1

Enter the partition menu by typing partition at the format> prompt.
format> partition

Display the slice information for the current disk drive by typing print at the partition> prompt.
partition> print

Exit the format utility by typing q at the partition> prompt and typing q at the format> prompt.

Verify displayed slice information by identifying specific slice tags and slices.

If the screen output shows that no slice sizes are assigned, the disk probably does not have slices.
